Cryptocurrency Portfolio Tracker

Adds an admin screen to enter in your cryptocurrency purchases and then exposes a simple to use shortcode and simple API to output your cryptocurrency portfolio’s performance on the frontend.

Please note that this plugin makes use of a 3rd party service to retrieve cryptocurrency prices. This means that a request is made to third party servers (coinmarketcap.com) requesting current cryptocurrency prices. See https://coinmarketcap.com/api/ for more information.

Simple usage:

Adding your portfolio

• Download, install and activate the plugin.
• Go to Settings > Cryptocurrency
• Set your fiat currency (USD by default and you can optionally set it to use the euro)
• Populate your coin purchases and your cost bases. You can enter multiple entries for the same currency (i.e. you have bought the same currency multiple times at different cost bases).
• ???
• Profit!… or look and see how to output the table on the frontend.

Outputting the data

Shortcode

[cryptocurrency_table] 

PHP API

cryptocurrency_table(); 

Filters

For the sake of brevity, by default, the table outputs (1) the current price of each currency and does NOT output the last time the price was retrieved (see API section below), both of which can be toggled by adding the following:

Hiding the current price:

add_filter( 'cryptocurrency/show_current_price', '__return_false’ ); 

Showing the last updated:

add_filter( 'cryptocurrency/show_last_updated', '__return_true' ); 

Changing how currency is displayed:

If you are using Euro as your fiat currency it defaults to outputting the € symbol after the amount, you can easily switch it to show the € symbol before by doing the following

` 

add_filter(‘cryptocurrency/currency_symbol_before’, function(){
return ‘€’;
} );

add_filter(‘cryptocurrency/currency_symbol_after’, ‘__return_null’ );
`

API

This plugin uses the public API made available by coinmarketcap.com. It is built to cache responses for 60 seconds so as to not flood the API. The plugin injects the last updated date/time as part of the response object which can be exposed via a filter (see Filters above). Please make sure to follow their API rules. See https://coinmarketcap.com/api/ for more information.
